Hmm...  About the big Ryouga-Ranma fight in
King of Nerima (Act II of Pursuit of Happiness...),
Ryouga shouldn't be able to do those Shishi houkoudans...

As depressed as he usually is, and as depressed as he can
make himself, life's been pretty good to him...  Especially
going into the fight, getting kissed by two cute girls in the
same afternoon...  Especially considering the second of those
was Ukyou, espcially considering that it probably reminded
him of waking up in bed kissing her, which, in anybody's opinion,
should put him in a quite deliriously happy mood...
Especially considering that he's thinking more of Ukyou (what
Ukyou said, which means Ukyou also) than anything during the
fight...  [Shrug]  Who cares.  I like it anyway.
